Basically i have drawn a pH titration graph on excel, and i have calculated a value on the x-axis from which i want to draw a line up so it touches the graph and then across to the y-axis, and could excel work out the value at that point on the x axis?
BTW- its a plot for weak acid strong base titration. Im trying to draw lines at the equivalence point and half equivalence point.
